This book is a contemporary statement of what is known about morphological development of the normal and abnormal human nervous system and puts into perspective the continued importance of changes that occur in the course of foetal development and how these processes may become defective. The first part of the book deals with the development of the central nervous system (CNS) from a morphological point of view including data from the fields of biochemistry, immunology and genetics. The second part reviews the genetic and nongenetic etiology of abnormal CNS development and discusses throughly all patologic syndromes that are related to disturbances of brain development. With the rapid progress in such modern branches of science as neurochemistry, genetics and molecular biology, this book will be invaluable for researchers working in these fields.
